ABSTRACT:
The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.
